Turgidity and rigidity in plant cells are primarily provided by the turgor pressure exerted by the vacuole against the cell wall. The large central vacuole in plant cells stores water and cell sap. When the cell absorbs water by osmosis, the vacuole swells, pushing the cytoplasm against the cell wall. The rigid cell wall prevents the cell from bursting, resulting in a firm, turgid state.

– Turgor pressure is the pressure exerted by the cell contents (driven by the vacuole) against the cell wall.
– The cell wall provides structural support and prevents bursting.
– Together, turgor pressure and the cell wall make the plant cell turgid and rigid.

Ribosomes are involved in protein synthesis. Mitochondria are the powerhouses of the cell, producing energy. The Golgi apparatus modifies, sorts, and packages proteins and lipids. None of these organelles directly provide turgidity or rigidity to the plant cell in the same way the vacuole and cell wall do.
